To all whom it may concern; 7

,Belit known that I, FRANK C. 'RINsoHE, a

citizen of theUnited States, residing-inthe city of St. Louis and State of Missouri, have invented certain'new and useful Improvements in Adding-Machines, of which the following is a specification.

- My invention relates to adding-machines; andhas for its object the improvement of the mechanism of such machines, whereby a more eflicient and uniform operation of the parts is secured.

The present invention is a general improvement upon the adding machines disclosed in my formrPatents No. 654,181 of July 24, 1900, and No. 751,207 of February 2, 1904, and is also a specific improvement upon the adding machine disclosed in my application filed Aug. 11,1906, Serial No. 33 ,175.

My improvements are illustrated in the accompanying drawings forming a part of this specification, in which Figure 1 is a section through the right hand side of my improved adding machine, showing my improvements completely assembled and in their normal position. Fig. 2 ma slmll-ar view showing the mechamsm in the position which it assumes when the operating handle is drawn completely forwvard. Fig. 3 is a detail drawing of m release mechanism, as shown from the le t side of the machlne and in its normal position. Fig. 4 1s a detail drawing of the same mechanism'just after being released; and

Fig. 5 is a detail drawing of the same mechanism in the position which It assumes .when the operating handle is drawn completely forward.

In the operation of my previous disclosures certain mechanism of the machines, including the movable type-carrying devices, has been arranged under such control of the operating handle, that it has been possible by the very slow or verrapid movement of the handle to give wi ely different rates of movement to the operating parts of the machine, so that it has been impossible to eliminate the danger of damaging some of the parts by rough handling. In this way some of the parts of the machine which might be made very light when used by one operator would necessarily be made much heavier when used by another operator and a more or less clumsy arwould necessarily follow.

In carrying out my present improvements, I provide means whereby the movable parts of the machine are actuated by Springs which are. released by a very slight forward movement of the operating handle and are again placed under tension by the complete stroke of the handle. It will thus be seen that no matter what the speed of operation of the'main handle may be, the movable parts are always actuated with the same governing force, viz., the tension in the above mentioned springs. I provide, as in my former disclosures, the main operating shaft 1 to be rotated by the handle or other convenient means-not shown in the drawingsand the segment .2 rigidly secured to such shaft. Also secured upon this shaft is the double arm 3, to either end of which the springs 4 and 5 are secured to normally hold the shaft in the position shown in Fig. 1. As in'my former patents, I alsoprovide the driving shaft 7,'but in my present invention I connect therewith the rigid link 8, which extends from the pivot 9 upon the segment 2 to the lower end of the arm 1.0, which is loosely mounted upon-the driving shaft 7. This arm 10, which is positively operated by the main handle, engages the catch 11 when the .handleis brought to its forward position,

as shown in Fig. 2, such catch being pivotally mounted upon the arm 12, and being held in its engaging position by the spring 13 between such catch and the arm 12, which is rigidly secured to the driving shaft 7. Upon the return of the handle, the arm 12 is drawn back to its normal position by the springs 4 and 5, which act to rotate the main shaft 1. V

Springs 14 are connected between the frame of the machine and the opposite ends of the arm15 upon the shaft 7, tending to rotate said shaft to the position shown in ig. 2, and are overpowered by springs 4 and 5 and moved to their 9 set position by the return motion of the main operating shaft. In order to allow this driving shaft to rotate from the position shown in Fig. 1v to that shown .in Fig. 2, I provide, as shown in detail in Figs. 3, 4 and 5, the dog 150 adapted to be engaged by the catch 16 and having a rotatable portion pivotally mounted in the arm 12, such portion carrying at its other end the flattened disk 17', against the flattened portion of which the projection 18 upon the catch 11 rests. Now, when the main operating handle is moved forward, the lower projection of the 4 dog 150' isengaged by the catch 16, thus rotating the disk 17 to its position shown in Fig. 4 and releasing the catch 11 from its engagement with the lower end of the arm 10. When thus released, the driving shaft 7 moves to its-forward position under the influence of 'springs 14, carrying with it the arm 12 and parts secured thereon. \Vhether the stroke of the main handle is completed or not at that time does not affect the movement of the driving shaft and parts controlled thereby, but upon the complete forward movement of the main operating handle the arm 10 moves into the position shown in Figsf2 and'5 and again engages the catch 11, which has been allowed to return to its original position by the movement of the dog 150, caused by the upper prong 19 thereof coming into engagement with the trip 20, shown inFig. 5, such trip being stationary and'so secured to the frame of the machine that it will engage the dog just before the arin 12 has reachedits forward limit of movement. It will now be seen that when the main 0 crating handle is released, the driving sha t will .be rotated back to' its normal position by the engage,

ment of the catch 11 with the end of the arm 10, and the machine will be in condition for the next operation.

In order to give uniformity to the motion of the parts controlled by the driving shaft,

the dash-pot 21 is provided, and through its' upon the'link 29, and thus prevent the main operating shaft from returning to its normal position until the catch 25 'lias been moved by the engagement of the rearward end 30 of lever 23 with the arm 31, which is rigidly secured to the catch 25. Such engagement, it will be seen will move the catch' 25 rearwardly and allow the main handle to return to its normal position.

The link 29 is connected by a link 29 to I the upwardly extending arm of the lever 10,

the two links forming a toggle joint. This toggle joint is normally broken as shown in Fig. 1 but when the handle of the ma chine has been pulled all the way forward the toggle joint is all but straightened as shown in Fig. 2. The effect is to relievethe hook or catch'25 by throwing the burden of resisting the main springs 4 and 5 upon the toggle. v

In order to prevent the main handle from being moved in the opposite'direction after its motion has been started in either direction and before .the stroke has been completed, I'- provide an improved form of ratchet, which consists of the notched periphery 32 of the segment 2 and the two similar. catches 33 and 34 connected by springs 35 and 36to the reversible-pawl 37, such. that-referring to Fig. 1the catch 34 alone engages the teeth 32 until the disk has been moved far-enough so that it moves the reversible pawl 37 upon its pivot 38,

gage the 'ratchet teeth 32 until't'he segment is moved. far enough for the catch 34 to no longer register with the ratchet teeth. As soon as the disk 2 strikes the reversible pawl 37 and rotates it, the catch 33 is raised by its contact with the extension 39 upon the pawl 37 and allows the disk to move catch 33. Upon the return movement of the handle the action of the parts is similar, except that the catches 33 and 37 now engage is moved away. by the movement of the reversible pawl 37. The arm 48, which is pivoted upon the frame of the machine at point 49', has the slot 40.. therein, in which the lug 41 carried on arm 15 moves and by its contact with the shoulder 42 at the end of the slot limits the rotation of the auxiliary shaft as caused by the tension of the springs 14.

In this specification I have only described.

such parts of my adding machine as are new, taken in connection with such parts as are old as are necessary fora complete understanding of my improvements; and

after which both catches 34 and 37 will enforward without coming in contact with the the ratchet teeth, while catch 34 while .I have shown and described my improvements of a specific form, it Wlll be understood that I' do not desire to be unduly limited thereto, as it is evident that other forms may be used without departing from the spiritor scope of the invention.
